To all whom it may concern.

Be it known that I, Sui-mums Vrmnm'r, a citizen of the United States. residing at, Los Angeles, in the county oi Los .Xngelcs and State of California, have invented a new and useful Rotary internal-Co1nbns tion Engine, of which the following is a specification.

The main object of the present invention is to provide a rotary internal combustion engine of simple construction and of great power for a given weight. I

Other objects of the invention will ap-- pear hereinafter,

The accompanying drawings illustrate an embodiment of my invention, and referring thereto:

Figure 1 is a plan view of the engine. Fig. 2 is an end elevation thereof. Fig. 3 is a section on line w a* in Fig. 4 is a section on line n1 0: in Fig. 0 5 is a vertical section of the engine. is a section on line ea -cc, Fig.

The engine comprises two casing members 1 and 2 mounted to rot-ate on shaft i which is supported on a frame 3. Each said casing members 1 and 2 is provided with an annular groove Tsemi-circular in cross section, and said casing members are secured together by fastening bolts 8 so that the two grooves '7 form an annular space divided by lixcd heads 9 into a plurality of cylinder chambers operating as the cylini'ler chamber The fixed heads '8) may be fixed to one or both of the casing members in any suitable manner, for example, i a

iiann'e. in the head engaging: in grooves.

10 in the casing members i and 9. Casino Jeniher l is provided with an nnvardiy et-e teruling; annular flange ii making Sildlilfl' 1c v fined on shai 't and contact will a dis i- 1 I to i iliiate assemblage. h casing t is e e mourned on shaft 4 )y a spidc i said t member and extending outside at (llSbI 12; Disk 19 is "formed with a 13 on one face, and the flange 11 has an extension 11 engaging in a rabbet 13 on this gear so that the flange 11 with its extension End the disk 12. together With the opposite casing: member snaee SQIYIfijI an intake chamber.

ihe engine herei n shown is adapted cooperate upon a 'fourstroke cycle and 'isjprovided With fonrheads J, dividing the annular chamber into four cylinder chambers ago, 0, (Z. Mounted in said cylinder clian' bee. oetvveen the respec tive heads 9 are pistons 14 carried bv cl;- tensions 16 on respective arms 16, lriosely mounted on the shaft 1 st) that said pistons H may reciprocate to and from the respective l'reads 9. Opposite'arms 16 may be connected to move in unison by mounting them on a hub 17. The pistons 14 are provided with packing rings 18. The extension 16 of each arm 16 extends thrbugh a slot 19 in the inner Wflllfif the corresponding cylinder chamber, and is U-sh'a'ped so as to embrace said wall when the piston lat is at the inner end of its stroke.

Each head 9 is provided with an intake port 22 having a valve 23 normally held closed by spring 24 and opening under suction in the adjacent working chamber to admit mixture from't he intake chamber 20 to said working chamber. An intake pipe 25 leading; to the chamber .20 aforesaid is connected to a carburcter 26 for supplying mixture to said chamber. An exhaust port 27 provided for each cylinder chamber a, 7), c. (Z, and ports 27 are provided in flange 11 registering with the ports 27, at proper times in the rotation, and are so arranged that the four cylinder chambers 11, b, 0, (l, are opened in sequence in each rotation.

Each of arms 16 is connected by a link 28 to a. crank 29 on a shaft 30, there being tour shafts G journaled on the rotating flange 1i aforesanl, and the respective shafts so carrying pinions 3i engaging with the gear .3 on shaft 4, so that in the rotation of the ii. the pinions 31 will roll around on iii" gear 13, and the cranks 29 will reve so as to ca sc the arms 16 to swing in snch man". er as to move the pistons 14 m and from t e heads 9, producing the Workin; strokes of the-engine. above described is flooded with oil contained in a chamber formed between disk 12 and flange 11.

E uitable imiiting devices. for example, spark plugs 35 are provided for the respective chambers 07, c, connected to suit-- The gen ring:

able energizing circuit timing means, not shown, for igniting the charges at the proper times.

The casing member 1 is provided with 5 suitable means such as pinion 38 for transmitting power from the engine.

The engine is shown as adapted to give five working strokes for each cylinder chamber per each revolution of the casing, and to give these strokes in sequence in the re spective cylinder chambers. For this purpose 'it is necessary to proportion the gears- 13 place only once in each revolution for each cylinder chamber. port 27 is required. I

To maintain fuel supply to the carburetor during rotation of the casing, the fuel inlet pipe 42 of the carbureter may communicate with an annular channel 41 in fixed shaft 4.- which communicates through passage 37 with the fuel supply pipe 36.

The operation is as follows: The engine being set in rotation. and the parts being in position as in Fig. 5 and turning to the right cylinder chamber 7) is starting on the compression stroke, cylinder chamber. 0 is starting on the expansion stroke, and cylinder chamber 01 is starting on the scavenging stroke. As the piston l i moves from the head 9 the valve 23 opens under the suction in said chamber, causing a charge of air and fuel to be drawn in through carbureter 26, chamber 20 and port 22. When. the casing has turned on c-fifth of a quadrant, the piston 14 is fully withdrawn and begins to approach the head, whereupon the valve 23 In that case only one closes and the charge is compressed, the operation being completed when the casing has turned two-fifths of a quadrant. At this moment the igniting device operates to explode the compressed charge and the piston 14: again moves away from the head 9, this being the working stroke and developing power both by forward pressure on the head 9 and by rearward pressure on the piston 14 which operates through the arm 16, link 28, crank 29 and pinion 81 to produce a retative action on the casing' This operation is completed when the casing is turned three-fifths of a quadrant, and during the ensuing one-fifth quadrant of a revolution, the piston again approaches the head 9 and the products of combustion are ejected through the ports 27 and 27, the ports 27 being so positioned that at this time one of nuance said ports is in register with the port 27 for the cylinder chamber a aforesaid. After one-fifth quadrant of further revolution, the cylinder chamber ahas advanced to the initial position shown in Fig. 5 for cylinder chamber 6, each cylinder chamber being onequarter phase in advance of the preceding cylinder chamber, so that the successive positions operate successively.

What I claim is:

1. In an internal combustion engine, a fixed shaft, a casing rotatably mounted on said shaft and provided with a plurality of circumferentially extending cylinder chambers, and with fixed heads between said chambers, pistons working in the respective chambers, gearing connected to the respective pistons to move the casing forward in the movement of the pistons to and from said heads. intake ports for the respective cylinder chambers, spring-operated valves for said intake ports opening automatically under the suction in said chambers, exhaust ports for the respective cylinder chambers, and fixed means having a sliding engagement with said exhaust ports and provided with'port means for opening the said exhaust ports in certain angular positions of the casing.
